We never checked for errors on add_disk() as this function returned void. Now that this is fixed, use the shiny new error handling.

The error handling is actually wrong, see https://lore.kernel.org/linux-scsi/c93f3010-13c9-e07f-1458-b6b47a27057b@acm.org/T/#t (local) Maybe you can base on that patch. Thanks, Ming
